Question

show that the diagonals of rhombus are perpendicular ​

Answer 1

Answer:

Proof that the diagonals of a rhombus are perpendicular

Proof that the diagonals of a rhombus are perpendicularCorresponding parts of congruent triangles are congruent,

so all 4 angles (the ones in the middle) are congruent. This leads to the fact that they are all equal to 90 degrees,

and the diagonals are perpendicular to each other.
